1. INSTRUCTIONS FOR USE

This heater shall not be operated unless the rock

compartment in the top of the heater is filled with the

rocks, and the guard is in place.

1.1. Piling of the Sauna rocks

The sauna rocks for an electric heater should be 1 9/16"

– 3 1/8" (4–8 cm) in diameter. The heater rocks should be

solid blocks of rock specially intended for use in the heater.

Neither light, porous ceramic “rocks “ of the same size nor

soft potstones should be used in the heater, because they

may cause the resistance temperature to rise too high as

a result of which the resistance may be broken.

Rocks dust should be washed off before piling the rocks.

The rocks should be piled into the rock compartment over

the grating, between the heating elements (resistances) so

that the rocks support each other. The weight of the rocks

should not lie on the heating elements.

The rocks should not be piled too tightly, so that air

can flow through the heater. See figure 1. The rocks

should be fitted loosely, and not wedged between the

heating elements. Very small rocks should not be put

into the heater at all.

The rocks should completely cover the heating elements.

However, they should not form a high pile on the elements.

The rocks disintegrate with use. Therefore, they should

be rearranged at least once a year or even more often if the

sauna is in frequent use. At the same time, any pieces of

rocks should be removed from the bottom of the heater,

and disintegrated rocks should be replaced with new ones.

The guarantee does not cover any faults caused by the

use of rocks not recommended by the plant. Neither does

the guarantee cover any faults caused by disintegrated or

too small rocks blocking the heater ventilation.

No such objects or devices should be placed inside the

heater rock space or near the heater that could change

the amount or direction of the air flowing through the

heater, thus causing the resistance temperature to rise

too high, which may set the wall surfaces on fire!

1.2. Heating of the Sauna

When the heater is switched on for the first time, both

the heater and the rocks emit smell. To remove the smell,

the sauna room needs to be efficiently ventilated.

The purpose of the heater is to raise the temperature

of the sauna room and the sauna rocks to the required

bathing temperature. If the heater output is suitable

for the sauna room, it will take about an hour for a

properly insulated sauna to reach that temperature.

See item 2.1., ”Insulation and wall materials of the

Sauna Room”. A suitable temperature for the sauna

room is about +150°F–+175°F (+65°C–+80°C).

The sauna rocks normally reach the required bathing

temperature at the same time as the sauna room. If the

heater capacity is too big, the airin the sauna will heatvery

quickly, whereas the temperature of the rocks may

remain insufficient; consequently, the water thrown on

the rocks will run through. On the other hand, if the heater

capacity is too low for the sauna room, the room will heat

slowly and, by throwing water on the rocks, the bather

may try to raise the temperature of the sauna. However,

the water will only cool down the rocks quickly, and after

a while the sauna will not be warm enough and the heater

will not be able to provide enough heat.

In order to make bathing enjoyable, the heater capacity

should be carefully chosen to suit the size of the sauna

room. See item 2.3. ”Heater Output”.

1.3. Control Unit

1.3.1. Timer

The heaters JM-17 and JM-20 are switched on by

using the timer switch. The indicator lights will come

on. The timer has two scales: the first one (with larger

figures) is the ”instantly on” section; that is, the

heater is on for a selected period of time (0–1 hours).

The other section is the so called ”pre-set section” (1–

8 hours), which is used to start the heater after a

certain time. The heater starts when the timer has

turned the switch back to the ”instantly on” section,

that is, at number one(1). After this, the heater will be

on for about 1 hour, unless the switch is turned to zero

before that. At zero (0), the supply to the elements is

cut off and the heater is switched off. See fig 2.

The JM-30 heater is equipped with 1 hour timer

without pre-set time function. See fig. 2.

If you wish to use the full 60 min. cycle, turn the

timer knob past the first 1 to number 2 or 3 on the

dial. Then turn backward to the large 1 until a click

is heard. Leave knob at that setting, and Sauna will

operate for 1 hour before shutting off automatically.
